transmitting a request signal that includes a sensor measurement range from a receiver to a transmitter;
determining at the transmitter the sensor measurement range included in the request signal;
providing at the transmitter that the transmitter is in the sensor measurement range; and
transmitting a reply signal from the transmitter to the receiver, the reply signal including a synchronization signal indicating a time base of the transmitter and data in the sensor measurement range.
2. The method according to claim 1 , wherein the data of the reply signal includes nibbles.
3. The method according to claim 1 , further comprising providing a length of the request signal based on the sensor measurement range.
4. A method comprising:
transmitting a request signal that includes a sensor identification coded into a length of a pulse in the request signal from a receiver to a transmitter, the sensor identification identifying a first sensor of a plurality of sensors;
determining at the transmitter the sensor identification based on the length of the pulse in the request signal; and
transmitting a reply signal from the transmitter to the receiver, the reply signal including a synchronization signal indicating a time base of the transmitter and data from a sensor identified by the sensor identification.
5. The method according to claim 4 , wherein the data of the reply signal includes nibbles.
6. A controller comprising:
a circuit to transmit a request signal over a communication path, the request signal including a sensor identification coded into a length of a pulse in the request signal to identify a first sensor of a plurality of sensors; and
the controller to receive a reply signal including a synchronization signal indicating a time base and data from the first sensor identified by the sensor identification.
